Transient thermal stress problem in an orthotropic, thin plate with a Griffith crack

Abstract

In this paper, the transient thermal stress problem for an orthotropic thin plate with a Griffith crack perpendicular to the surfaces of the plate is considered. It is assumed that the transient thermal stress is set up by the application of heat flux to the surfaces of the crack and the heat exchange by convection on the surfaces of the plate. The analytical solution is found by Airy stress function. Numerical results indicate a dependence of the orthotropic stress intensity factors on the thermal and elastic constants over a certain parameter range.
